Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water electroplating of plastic parts, in particular to a hanger for water electroplating of plastic parts. Background Art
[0002] Water electroplating of plastic parts is a surface treatment technology that is mainly used to improve the aesthetics and functionality of plastic parts. Among them, commonly used plastic parts include sealing rings.
[0003] Sealing ring plastic parts are generally directly injection molded in one piece through an injection mold, and then water electroplated in an electroplating tank. The electrochemical reaction is used to form a uniform coating on the surface of the sealing ring plastic part to improve the smoothness and aesthetics of the surface of the sealing ring plastic part.
[0004] When performing water electroplating operations on sealing ring-type plastic parts, a hanger is needed to hang a certain number of sealing ring-type plastic parts on the hooks of the hanger, and then each sealing ring-type plastic part hung on the hanger is placed into the electroplating tank through the cylinder to achieve the later water electroplating effect.
[0005] At present, when all the sealing ring-type plastic parts on the existing hanger for water electroplating of sealing ring-type plastic parts are placed in the electroplating tank, the sealing ring-type plastic parts may be affected by the buoyancy of the electroplating liquid due to the presence of electroplating liquid in the electroplating tank, and some of the sealing ring-type plastic parts may slide upward and detach from the hook. After the water electroplating is completed, the partially detached sealing ring-type plastic parts need to be fished out by the staff, which greatly reduces the anti-slip and detachment performance of the hanger for water electroplating of sealing ring-type plastic parts.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0027] Refer to Figures 1-5 , a hanger for plastic part electroplating with water, including a hanger frame 1, a hanger 5 is arranged on the hanger frame 1, an electroplating tank 2 is arranged below the hanger frame 1, cylinders 3 are arranged on both sides of the electroplating tank 2, a drain pipe 21 is arranged on the electroplating tank 2, a lifting plate 31 is arranged on the cylinder 3, and a central pillar 32 is arranged on the lifting plate 31;
[0028] An anti-detachment retaining rod 7 is inserted on the hanger 5, a welding seat 6 is arranged on the hanger 5, a rod handle 8 and a spring 81 are arranged on the anti-detachment retaining rod 7, and a positioning groove 51 is opened on the hanger 5;
[0029] The central pillar 32 is fixedly arranged with the hanger frame 1, an outer rib plate 4 is arranged on the hanger frame 1, an inner rib ring 41 is arranged on the outer rib plate 4, the electroplating tank 2 is a prior art, some existing structures are not drawn and marked, and the electroplating principle with water is also a prior art, which will not be elaborated.
[0030] A clamping groove 53 is opened on the hanger 5, a damping anti-slip sleeve 531 is arranged in the inner groove wall of the clamping groove 53, the damping anti-slip sleeve 531 is squeezed and sleeved with the anti-detachment retaining rod 7, an arc chamfer 52 is arranged on the hanger 5, and a smooth layer 521 is arranged on the arc chamfer 52. The smooth layer 521 is a graphite coating layer, with a flat and smooth surface. Combined with the arc chamfer 52, it improves the smoothness and quickness of hanging the sealing ring type plastic part onto the hanger 5.
[0031] The fixture 5 is in an overall hook-shaped structure. The positioning groove 51 is an arc-shaped inner groove that runs longitudinally through the fixture 5. An elastic cushion 511 is provided on the inner groove wall of the positioning groove 51. The elastic cushion 511 is a polyurethane material cushion layer with high elasticity, which improves the buffer and elastic protection effect when the sealing ring type plastic part is hung into the positioning groove 51.
[0032] A perforation 61 is provided on the welding seat 6, and a horizontal sliding hole 54 is provided on the fixture 5. An elastic anti-wear sleeve 71 is provided on the outer wall surface of the anti-detachment stop rod 7. One end of the elastic anti-wear sleeve 71 facing the horizontal sliding hole 54 is provided with an inclined chamfer 72. The elastic anti-wear sleeve 71 is made of NBR nitrile rubber material, which has high elasticity, corrosion resistance and wear resistance. When the sealing ring type plastic part floats, it will collide and rub against the elastic anti-wear sleeve 71, which improves the durability of the anti-detachment stop rod 7.
[0033] Combined with the inclined chamfer 72, the elastic anti-wear sleeve 71 can be smoothly squeezed and inserted into the horizontal sliding hole 54.
[0034] A spring 81 is arranged between the welding seat 6 and the rod handle 8. The rod handle 8 is provided with a finger pulling groove 82. The finger pulling groove 82 is a symmetrically arranged arc-shaped groove, which is convenient for the two fingers of one hand to hook in and pull.
[0035] A damping layer 821 is provided on the inner wall of the finger pulling groove 82. The damping layer 821 is a silica gel pad with damping elasticity, which avoids the fingers from slipping in the finger pulling groove 82 and improves the elastic comfort when the fingers are pulled.
[0036] The fixture rack 1 is in an overall rectangular structure. There are four outer rib plates 4 arranged in a circular pattern. The included angle between the outer rib plates 4 and the horizontal plane is 45 degrees. The 45-degree inclined structure has the stability of a triangle. Both the outer rib plates 4 and the inner rib rings 41 are made of hard alloy steel, with high strength, no deformation and durability.
[0037] The inner rib ring 41 is in an overall arc-shaped ring structure. There are four inner rib rings 41 arranged in a circular pattern and fixedly arranged with the outer rib plates 4. The two ends of the inner rib ring 41 are fixedly welded to the outer rib plates 4 respectively, which further improves the structural stability of the outer rib plates 4.
[0038] Working mode: First, insert the finger into the finger-pulling groove 82 and pull it to the right, driving the anti-slip lever 7 to slide to the right and exit the clamping groove 53 and slide into the horizontal sliding hole 54. Stop pulling the finger-pulling groove 82. At this time, the spring 81 is stretched and deformed. Then, pass a sealing-ring type plastic part through the arc chamfer 52 and hook and slide it into the clamping groove 53. Withdraw the finger from the finger-pulling groove 82, and the spring 81 pulls back, driving the anti-slip lever 7 to quickly squeeze and insert into the clamping groove 53 to hook the remaining sealing-ring type plastic parts on the matching hanger 5. Then start the cylinder 3 to drive the hanger frame 1 to move downward. When all the hangers 5 and the sealing-ring type plastic parts are immersed in the electroplating solution in the electroplating tank 2, stop the cylinder 3, and the subsequent operations of electroplating can be carried out (which is the prior art). Since the electroplating solution has buoyancy, it is easy for some sealing-ring type plastic parts to slide upward on the hanger 5. At this time, the anti-slip lever 7 functions to block, preventing the sealing-ring type plastic parts from sliding off the hanger 5 due to buoyancy, thus improving the anti-sliding and anti-detachment performance of the hanger 5 for electroplating the sealing-ring type plastic parts.
[0039] In addition, by providing a structure of an outer rib plate 4 with an inner rib ring 41 between the hanger frame 1 and the lifting plate 31, the structural stability between the hanger frame 1 and the lifting plate 31 is greatly improved.
[0040] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
